Hoox, AUTOMATIC RELEASING.

fo all whom t may concern Be itknown that I, Or'ro T. HENRIKSON, a citizen of the United States, residingl at Chicago, in the county of Cook yand State of Illinois, have invented a certain new and useful Improvement in Hooks, Automatic Releasing, of which the following is a` full, clear, concise, and exact description, reference being had to the accompanying drawings,`forminga part of this specification.-

The invention relates to automatic hooks and primarilykto that class of these devices which' are automatic in their releasing action. The object' of the invention is'the production of v.a' device of this character which will be simple in construction and operation, and which will v'not, result inta corresponding reduction inefliciency. y

The device herein shown and' described is designed to b e capable of securely holding an obj ect while same is being lifted and transported from one ,position to another, and which .will automatically release the object upon its beingplaced lat its desired destination, thereby eliminating the necessity of the attention of ,a vperson at the place that the object is to be deposited. l

I will explain the invention more'in detail by reference to the drawings, in which- Figure 1 is a perspective view of my im-l proved hook,

Fig. 2 is a perspective view of a modification of the device shown in Fig. 1; 'Fig 3 is a side elevation of a portion of another modified form of construction, and Fig. 4 is a View showing a means whereby the device may be locked against separation when desired.

Referring. to the drawings, and particularly to Fig. 1, I show a pair of toggle members 10 and 11 and a cross bar 12 coperating therewith. The member 10 is provided at one of its extremities with the eyelet 13 which. forms -a .convenient means whereby the device may be secured to a chain or cable.

(not shown),` and suspended therefrom. This member 10 is further provided with the flattened apertured portionsv 14 and 15 which form convenient points of attachment for the members 11 and 12. The member 11 is pivotally secured at 14 to the member 10 by means of the bolt or pin 16, this member being provided at its opposite extremitles with the counter weight 17 and the pin 18. This pin is designed to coperate with the Specification of Letters Patent.

member 12 in a manner presently to be descr1bed.

- The cross member 12 is pivotally secured to the member 10 at 15 and projects out-v.

wardly therefrom toward-the pin 18 of the member 11 and engages said pin when the parts are placed in operative relation to each other. The end of the member 12 remote from its pivot is provided with the curved end portion 19 which forms a cam' surface which'with the coperation of the pin 18 tendsto move the lever 11 inwardly when a strain -is exerted upon the member 12. It will be understood that the curve of this portion 19 'is not so great as to interfere with the operation' of the device in its proper manner. The 4member 12 forms a convenient means'whereby a link or hook 20 of the article to be ,supported may be engaged and released when the article is desired to bev lifted or deposited. v In the modified form shown in Fig. 3,v a spring-21 is shown which re-acts between the end of the member 1.1 and ythe member 10, this being equivalent in its action to the counter weight 17.

In the form of device shown in Fig. 2', the construction is similar to that shown in Fig. 1, but differs therefrom in that the member 11 isprovided with the weight 22 at the end nearest the end of the member 12 instead of remote therefrom as in the device shown 'in Fig. 1. This device also differs slightly a part, as is evident immediately upon the release of the pulling strain of the chain, the

parts 18 and 19 will become disengaged from each other, due to the'tendency of the member 11 to swing away from the member 12, thereby releasing the connection between the end 19 of said member and the pin 18 of the member 11.

It will be understood from the foregoing explanation of the construction` of the device that as long as a pulling strain is exerted upon the several parts, same will maintain the relation to each other as shown in full lines in Figs. 1 and 2, and immediately upon the pulling action being eliminated, the pin 18 of the member 11 will be forced by the weight 17'o1j 22 from engagementlwith the end of the member 12, permitting the member 12 to swing away from the member l1. This position of rthe .'parts.' allows the link to disengage itself or slide away from the member 12 and releasefthearticle'to Vwhich the hook tached.l

The construction shown in Fig.l 4f illustrates a -means whereby the parts 11 and 12 maybe lockedvtogether to prevent the operation of the device as hereinbeforecmentioned, Then this construct-ion is desired the end of the member 12 will be slottedas shown at l23 and the' wedge shape -keyQ/l ,pivoted thereto, whichwhen positioned` as shown .prevents the arm. 11 from becoming .disengaged from` theI v cross arm v12. When the device vis desired to be used in the ordinary. way the key will'fbevpositione'd 4as .shown in dotted lines, whichA permitsthe parts to become disengaged from eachother ,whenfthe pullingfstrainis released fromv said -memben Y f 1 .25k
